Broadcast media in the 1920s Broadcast media includes radio and
radio and
television programs. Television includes
cable television, which may require a
cable converter box, and generally includes
subscription-based channels and
pay-per-view services.
Digital radio and
digital television may also transmit
multiplexed programming, with several channels
compressed into one
ensemble.
Broadcast regulations, Films are produced by
recording people and objects with
cameras, or by creating them using
animation techniques or
special effects. Films comprise a series of individual frames, but when these images are shown in rapid succession, an illusion of motion is created. Flickering between frames is not seen because of an effect known as
persistence of vision, whereby the eye retains a visual image for a fraction of a second after the source has been removed. Also of relevance is what causes the perception of motion: a psychological effect identified as
beta movement.
Video games A video game is a computer-controlled game in which a video display, such as a monitor or television set, is the primary feedback device. There must also be some sort of
input device, usually in the form of
button/joystick combinations, a keyboard and mouse combination, a
controller, or a player's motion.
Audio recording and reproduction Sound recording and reproduction is the
electrical or mechanical re-creation or amplification of
sound, often as
music. This involves the use of
audio equipment such as microphones, recording devices and loudspeakers. From early beginnings, with the invention of the
phonograph using purely mechanical techniques, the field has advanced with the invention of electrical recording, the mass production of the
78 record, the magnetic
wire recorder followed by the
tape recorder, and the vinyl
LP record. The invention of the
compact cassette in the 1960s, followed by Sony's
Walkman, gave a major boost to the mass distribution of music recordings, and the invention of
digital recording and the
compact disc in 1983 brought massive improvements in ruggedness and quality.
Internet media The
Internet is a more interactive medium of mass media, and can be briefly described as "a network of networks". Specifically, it is the worldwide, publicly accessible network of interconnected
computer networks that transmit
data by
packet switching using the standard
Internet Protocol (IP). It consists of millions of smaller domestic, academic, business and governmental networks, which together carry various
information and services, such as
email,
online chat,
file transfer, and the interlinked
web pages and other documents of the
World Wide Web. The Internet is the system of interconnected
computer networks, linked by
copper wires,
fibre-optic cables, and
wireless connections, while the Web is the contents of the internet linked by
hyperlinks and
URLs. The
World Wide Web is accessible through the Internet, along with many other services including e-mail,
file sharing and others described below. Toward the end of the 20th century, the advent of the World Wide Web marked the first era in which most individuals could have a means of exposure on a scale comparable to that of mass media. Forms of internet media include
blogs,
microblogs,
RSS feeds, and
podcasts.
Mobile Mobile phones were introduced in
Japan in 1979 but became a mass media only in 1998 when the first downloadable ringing tones were introduced in Finland. Soon most forms of media content were introduced on mobile phones,
tablets and other portable device. Similar to the internet, mobile is also an
interactive media.
Print media Magazine on the cover for Al-Mawwid magazine, June 1972 A
magazine is a
periodical publication containing a variety of articles, generally financed by
advertising or purchase by readers. Magazines are typically published
weekly,
biweekly,
monthly,
bimonthly or
quarterly, with a
date on the cover that is in advance of the date it is actually published. They are often printed in colour on
coated paper, and are bound with a
soft cover.
Newspaper in
Washington, D.C., showing newspaper headlines from the day after
9/11 A
newspaper is a
publication containing news, information, and advertising, usually printed on low-cost paper called
newsprint. It may be general or special interest, and is usually published serially, most often daily or weekly. The dominant function of newspapers is to inform the public of significant events. Newspapers originated after the invention and spread of the
printing press by
Johann Gutenberg around 1450, with the first newspaper being the German-language
Relation aller Fürnemmen und gedenckwürdigen Historien, first published in 1605. The increasing prevalence of internet-based news media has, while challenging newspapers as an alternative source of information and opinion, has also provided a new platform for mass media organisations to reach new audiences. As such, in the twenty-first century, newspaper circulation has fallen in almost all regions.
Outdoor media in 2019 Outdoor media is a form of mass media which comprises billboards, signs, placards, flying billboards, blimps, skywriting, and
augmented reality advertising. Many commercial advertisers use this form of mass media when advertising in sports stadiums. == Professions ==
